Stretching Cells for Calcium (VIDEO) Duke University This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption This movie depicts cells being stretched by cavitation bubbles sent from various distances over a 3.5 minute span. The calcium responses of cells are at the top and the ability of a dye to permeate cell membranes is at bottom. Understanding these types of details will help researchers better tailor ultrasonic therapies that use cavitation bubbles to affect cells.
